Daug-Dagoth, Werebeast-Demon of the North
In the year circa 2000 Farland Reckoning, Daug-Dagoth the Ravager, also called the Terrible, the Hunter, and the Slavering, came like a plague into the North. He was originally a powerful Oni Mage from the lands East of the Wintervale, which are controlled by the Dweller. Dagoth served in the Dweller's army and attended her in her pits and under-fortresses, before the Dweller chose the Oni for a mission of particular importance. What that mission was remains a mystery. Infecting him with the curse of lycanthropy from a cave bear, the Dweller sent forth this new horror. Daug-Daugoth came ravaging. He laid waste to the countryside, slaying elves and men. This terror went on for a year, and all cowered and hid in the face of the slavering Bear-demon; none could stand against him. The more time that Dagoth spent in his Were-bear form, however, the more of his intellect he lost, and the more insane he became, forgetting to use his spells. Eventually he forgot his mission and set about killing indiscriminately, remaining in his bear form almost constantly. Finally, however, the elven Hero Menelrim of house Featar tracked the beast and slew him. Thus passed the terror of Daug-Dagoth from the face of the lands.
In Oni Mage form, Dagoth is similar to any other Oni. He is, however, of particular cunning and power, and he wears a chain shirt and carries a black greatsword. In cave bear form, however, he is more terrible. His form is almost fully that of a huge brown cave bear, nearly 16 feet tall and 2000 pounds. Its face, however, is still faintly Oni-like, yet with huge fangs, and slobber dripping and splattering from its jaws. Chaos and madness gleam in its eyes; its fur is disheveled and dirty and the stench of death wafts from its jaws and fur.
